- duits for protecting and supporting the elec- 4 trical conductors ofan ignition system such as employed with internal combustion engines. Myinvention contemplates the provision of a pairof cooperating membersforming halves of a tube or conduit through which the electricalconductors pass. -One of the halves in the preferred form of myinvention is provided with a plurality of outlet openings through whichthe free ends of the electrical conductors may pass to their respectivespark plugs of the engine. In use the conductors are brought togetherand the free ends of the conductors are brought through the openingsprovided in one of the conduit members, after which the other conduitmember is fitted into the first member to inclose the conductors.Suitable caps are provided for each end of the mani- Fig. 2 is afragmentary elevational View of one side of the ignition manifold;

showing the opening which permits the admission of the conductors; and

Fig. 4 is an enlarged sectional detail view of the device taken on theline 4-4.- of Fig. 2.

The drawing Fig. 1 illustrates a six cylinler automobile engine 9 havingspark plugs 10 to 15 inclusive, each connected with an associated enginecylinder for igniting the charge within the cylinder. At 17 Ihave showna distributor of conventional type having conductors leading to thespark.

plugs. The conductors are connected at one end to the contacts of thedistributor, and have free ends 18 to 23 inclusive. The conductors passfrom the distributer '17 through the ignition manifold 25 supported bysuitable clamping members 26 and 27 attached to the engine frame. Themanifold 25 comprises two halves 28 and 29 and as shown most clearly inFigs. 2 and 4, the member 28 is enlarged from a semi-circular crosssection, as shown at 30 and 31, to admit the member 29,which is alsosemi-circular on cross section. The member'28 is provided with outlets33 one for each spark plug, and in order to protect the conductorsextending through the outlets I have found it desirable to form thematerial surrounding the outlets with a rounded portion 34 to preventthe wear which would result from having a sharp edge surrounding theoutlets. To retain the members.28 and 29 in closed ositioncaps areprovided for each end 0 the manifold, and the cap 37 for the inlet endof the manifold is provided with an opening 38 large enough to admit thewires'from the distributer. f desired, the cap 39 at the opposite end ofthe manifold may be provided' with an opening through which a conductormay extend. In assembling and attaching the device the conductors arebrought together and the cap 37 is slipped over the wires to a pointnear the distributer. The section 28 is then brought adjacent theconductors and the free ends thereof 18 to 23 inclusive are insertedthrough the openings 33 and connected to their respective spark plugs.The member 29 is then inserted between the flanged portions 30 and 31 ofthe member 28. The caps 37 and 39 are then slipped over the ends of themanifold, which holds the two sections in aclosed position. The entiredevice will be supported by the clamping members 26 and 27 and theconductors will be protected and supported in the desired position.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United- States is:

1. In combination with an automobile engine having anignition system, anignition manifold comprising two halves, one of said halves adapted tofit with the other of said an inlet opening for said conductors, a capfor each end of said manifold, one of said halves being provided withbranch open ings, and means adjacent said openings to prevent chafing ofthe conductors".

2. A manifold for internal combustion engines comprising two cooperatingmembers together forminga tube, means for retaining said members inposition with respect to each other, one of said cooperating membersbeing provided with 'a pluralitypf outlets, the material adjacent saidoutlets being rounded to prevent chafing of the conductor passingthrough the outlet.

3. An ignition manifold for internal combustion engines, comprising apair of sections forming a longitudinally split conduit for receivingthe distributing conductors,

one section of said conduit being provided with outlet openings, andmeans detachably securing the sections of said conduit together.

4:. A manifold for the distributing conductors of an internal combustionengine, comprising a conduit longitudinally split into a pair ofsections, theed es of one section of said conduit being 0 set to receivethe edges of the other section, one of said sections being provided witha plurality of outlet openings, and means for detachably securing thesections of said conduit together. a

In witness whereof, I hereunto subscribe my name this 8rd day of J une,1918.
